  • Biocide compositions comprising quaternary ammonium and urea and methods for their use
    Patent number: 9445598
    Abstract: Composition and method for treating and/or preventing biological contamination using a biocide composition comprising at least one quaternary ammonium compound and urea. The method includes drying urea, and thereafter combining at least one quaternary ammonium compound and urea and may produce a potent biocide composition that is stable and able to chemically treat biological contamination in a variety of difficult to reach locations. Uses of the composition are also described.

  • Cutting device having a flexible cutting element
    Patent number: 4258763
    Abstract: A plurality of cutting teeth are disposed at intervals in a complete circle around the periphery of a flexible cutting element. A frame is coupled to the cutting element to receive and guide the cutting element. Means is coupled to the cutting element and to the frame to impart an oscillatory motion to the cutting element to enable the oscillating teeth of the cutting element to cut a selected material. A simplified version of the present invention includes first and second handles coupled to opposite ends of the flexible cutting element to enable an operator to impart an oscillatory motion to the cutting element.
